Storyboard-Text
- Hi Vidhi! The weather is so hot these days. Even are schools have been closed early due to such hot weather.
- Hi Riddhi! The reason is global warming due to carbon dioxide emission.
- I can't understand. Can you please explain me?
- Carbon dioxide (CO2) is a greenhouse gas. This means that it causes an effect like the glass in a greenhouse, trapping heat and warming up the inside.
- But how is it related with the temperature on earth
- When energy from the Sun reaches the top of our atmosphere,most of it passes through to earth's surface, where it is absorbed. Some of this energy is re-emitted heading back towards space. At this stage, it interacts with molecules of CO2 in a way that prevents some of it from escaping Earth's atmosphere. The trapped heat energy leads to increased air temperatures.
- What is the use of this greenhouse effect?
- This effect is very important without the CO2 that naturally exists in the atmosphere, Earth might be too cold to support human life.
- This greenhouse effect has been going on our earth for a long time but then why are we suddenly feeling so hot this time?
- Because of excess carbon dioxide emission by us humans. We use vehicles and run big factories on a daily basis which releases excess of carbon dioxide gas.
- I didn't that carbon dioxide gas had such a big impact. Thank you for explaining me.
- One reason carbon dioxide has such a big impact on global temperatures is that hotter air can hold more water vapour. Water vapour is itself a greenhouse gas, which further enhances the greenhouse effect. Your Welcome
